Various Questions

[sm3570]

Alright fellas, a couple questions:

1) I need a heat riser tube (the flex tube that goes from the air filter assembly inlet to the exhaust manifold). I'm not interested in concours necessarily, what's a good inexpensive substitute? Of course, NOS or repop is fine too, but I'm having a hard time finding it.

2) I have a Holley carb with a 3/8" PCV port. The stock PCV hose appears to be larger than 3/8" hose, what have you guys used? Note: this is for a 429, not sure if the PCV valve on the 351's are different.

3) My fuel vapor charcoal canister is gone, and I know they aren't repop'd. Anybody have one?

4) The very bottom of the throttle linkage on my carb is hitting the intake manifold. Nothing is hooked up to it in that area (it's a Holley 4160, universal application), think I can trim the bottom off so it doesn't hit any more? Right now I can't take it to full throttle, probably about 90% travel.

Thanks guys!

I got my heat riser tube at NAPA. I just told them the diameter and they produced it.

On my Cleveland, my linkage was hitting my intake and I ended up having my intake on backwards. OOPS! Not sure if thats possible with a 429 or not? But I added a 1 inch spacer under the carb to fix the problem, then figured out it was backwards and switched it around. Bonehead moment! Works fine now.

Spacer or trim it

BUT get it fixed before it sticks at 90% open throttle

Thanks guys!

Get a spacer. Mine is one inch aluminum, some of them have an additional vacuum port usually for brake or PVC. A spacer also helps to mix the gas/air flow better.

Forgot to mention, also helps keep the carb cooler. Thanks c9zx.

Something like this http://www.summitracing.com/parts/EDL-9266/ may give you the clearance you need and provide heat isolation for the carb. Chuck

What I did for my 460 in my 78 F250 is I bent a PVC tube out of mild steel and used two short pieces of hose to connect it. I also used a spacer on my 460 so I could use a Eelbrock square bore carb. The spacer I used had a port for the PVC in the front so this is why mine went the way it did. I wish I had a better picture of it since I am not able to take another photo of it, sold the truck over a year ago.

Thanks for all the replies guys. I found the heat riser tube locally, so no biggie there. Don I'll be e-mailing you an order in the next week or two, I'm sure! I was thinking of putting a spacer on the carb but I dunno, maybe I'll trim the throttle linkage. Since it's a universal carb it's got a lot of extra holes and stuff for all the different manufacturers. The intake is on right so that's not an issue.

It's been a long day of wrenching on the engine, and I'm frickin' exhausted so I'm going to get back at it tomorrow. Right now I'm enjoying a Captain and Coke!

Alright guys, FYI the bottom of the throttle linkage is for mounting a Chrysler adapter. Not used in Ford applications, so I trimmed it off with a Dremel. No more obstruction.

Also, the PCV valve is 1/2", so I found a 1/2"-3/8" adapter and used hose clamps with a 3/8" hose. Nice fit, doesn't look the best but when I pull the engine to rebuild it I'm going to take care of all the under hood ugly-ness.

Fired it up and took it for a spin, it is running awesome!

One question for the techie guys, my 429 is drawing about 14" of vacuum, is this a good number? I didn't adjust the timing on it and it's running great, just a little rich because I have to re-jet the carburetor.

Also, I have to rewire the electric choke (going to wire it to the keyed accessory fuse block (20A fuse) and have a 10A fuse wired inline. This shouldn't be too bad of a job.

Thanks again for all your replies and help!

If it is a stock cam that seems a bit low. I would expect 17-18 with a stock cam. If it is not stock 14 could be normal, it depends on the cam. If the jetting is way off it could cause the vacuum to be low also. Chuck

 

[sm3570]

I believe the cam is stock, my understanding is that the whole engine is stock. I haven't torn into it so I'm not 100% sure. Once I rejet the carb I'll retune it and see what I get. Thanks Chuck!

Well, after jetting down the Holley and doing a little tuning I am now pulling 15" of vacuum (no jokes ROY ). I checked to make sure all the vacuum plugs and hoses are tight. I'm not sure exactly how accurate my gauge is though. It's a pretty solid 15", every now and then it will dip down about 1/2" or so (maybe less) then right back up to 15". I tried advancing the timing a little but it didn't gain me anything.

Is there anything else I should look at? It's idling nice and has some acceptable get-up-and-go, but I'd like to get every drop of performance out of the current configuration that I can.
